Unlinking /dev/null is bad, we shouldn't do that. Also, we should print
at least a warning if we tried to unlink a file but didn't manage to
pull it of (ignoring the case were the file is /dev/null or doesn't
exist in the first place).
This got triggered by a relatively unlikely to cause problem in
pkgAcquire::Worker::PrepareFiles which would while temporary
uncompressed files (which are set to keep compressed) figure out that to
files are the same and prepare for sharing by deleting them. Bad move.
That also shows why not printing a warning is a bad idea as this hide
the error for in non-root test runs.

Our error reporting is historically grown into some kind of mess.
A while ago I implemented stacking for the global error which is used in
this commit now to wrap calls to functions which do not report (all)
errors via return, so that only failures in those calls cause a failure
to propergate down the chain rather than failing if anything
(potentially totally unrelated) has failed at some point in the past.
This way we can avoid stopping the entire acquire process just because a
single source produced an error for example. It also means that after
the acquire process the cache is generated – even if the acquire
process had failures – as we still have the old good data around we can and
should generate a cache for (again).
There are probably more instances of this hiding, but all these looked
like the easiest to work with and fix with reasonable (aka net-positive)
effects.

The parameter name suggests that it should forbid the building of the
entire cache in memory, but this isn't how it was previously and as
AllowMem is false by default it actually prevents previous usecases from
working like being root and configuring apt to build no caches at all.
This should be fixed at some point to actually work, but that is hard to
pull off as it means switching the default and some callers (including
apt itself) actually did call it explicitly with false in certain
cases for no apparent reason (at least now where it is common to have
enough memory to throw at every problem and even if not is a slow apt
usally better than an apt erroring out).

Currently, this always returns true, but it might start returning
false at some point in the future...

Further abstracting our new ShowList allows to use it for containers of
strings as well giving us the option to implement an or-groups display
for the recommends and suggests lists which is a nice trick given that
it also helps with migrating the last remaining other cases of old
ShowList.

Various small leaks here and there. Nothing particularily big, but still
good to fix. Found by the sanitizers while running our testcases.

This partly reverts d059cc2 and fixes bug #753297 in a more
general way by ensuring that CacheFile.BuildDepCache() builds
a pkgPolicy if there isn't one already.

Beside being a bit cleaner it hopefully also resolves oddball problems
I have with high levels of parallel jobs.

- move the RunScripts() code into fileutl.{cc,h}

- add support for "APT::Update::{Pre,Post}-Invoke" scripts

'apt-get update' no longer does 'Building Dependency Tree'.
